COUPLING.

' Specification of Letters Patent.

Patented Oct. 15,1912.

To all whom it may concern:

Be itknown that we, ALBERT O. GALE and ELDoR J. IvnRsoN, both citizensof the United States, and residents of Seattle, in the county of Kingand State of VVashington, have invented certain new and usefulImprovements in Couplings, of which the following is a full, true, andexact specification.

The principal object of this invention is to provide simple, effectiveand quick acting means for coupling together the ends of hose, lineshafting, or the like, and in the operation of which no wrenches orother tools are necessary.

Referring to the accompanying drawing, Figure 1 is a side elevation ofour device in locked position. Fig. 2, an end elevation of the same.Fig. 3 is a central longitudinal sectional view of Fig. 1. ,Fig. 4-, aside ele vation of the righthand locking member. Fig. 5, a sideelevation of the corresponding lefthand member. Fig. 6, a side elevationof the collar, partly in section. Fig. 7 a side elevation of the cap,partly in section. Fig. 8, an end elevation of Fig. 7, looking towardthe left. Fig. 9, a side elevation of the two principal locking membersin locked engagement of each other, and stripped of the other parts. 4

Referring now more particularly to the drawings, the numeral 1designates a central core which, if the coupling be used for hose, maybe hollow, as shown, and to the lefthand end of which may be attached inany suit-able manner, one of the sections of hose to be coupled. Aroundthe outer surface of the core 1, and firmly secured thereto, are theoppositely disposed curved plates 3, projecting from which are the studs4. The righthand end of the core 1 is tapered as at 5.

6 designates a collar, having the annular knurled rib 7 annular groove8, and cam slots 9. From the internal surface of the collar 6, andextending toward the center thereof, are the oppositely disposed raisedportions 10.

11 designates a cap which is bored to fit the lefthand end of the collar6, and in which are the screws 12, which fit and wipe around in theannular groove 8 of the collar 6. The end of the cap 11 is counter-boredas at 13, to fit the core 1. Extending from the end of the cap 11 arethe tongues 13*.

14 is the righthand locking member,

outer end of which may be suitably connected the hose to be coupled,and, for convenience in handling may have the annular rib 15.- Extendingfrom the lefthand end of the locking member 14 are the oppositelydisposed shell-like projections, 16, which are substantiallycounterparts of the plates 3, of the core 1. The plates 3 and theextensions 16 are of equal thickness and repwhich may be bored as at 14and to the resent arcs of the same circle,rthe former adapted to enterthe spaces between the latter (Fig. 9).

If Fig. 3 be considered especially in conmotion with Fig. 9 it will beseen that the co-re 1 and the righthand locking member 14, when in thepositions there shown, can have no rotary movement with relation to eachother, the projections 16 ofthe righthandlocking member 14, the tongue13 of the cap 11 and the plates 3 of the core 1 being substantially incontact with each other, and encircling the core 1; neither canlongitudinal movement occur, the same being prevented by the engagementof the studs 4 with the slots 9 of the collar 6. If either the core 1 orthe righthand locking member 14 be now held against rotation and theknurled rib 7 upon the collar 6 turned in the direction of the arrow,Fig. 2, until the studs 4 reach the offsets 17 in the slots 9, the core1 and the member 14 may be drawn apart until arrested by the contact ofthe studs 4 with the righthand edges of the slots 9, when the rotationof the collar 6 may be continued until again arrested by the contact ofthe studs 4 with the ends of the slots 9. During this entire rotationthe slight cam action of the slots 9 upon the studs 4 has forced thecollar 6 and its cap 11 together with its tongue 13 toward the left,withdrawing the free ends of the latter from between the plates 3 of thecore 1 and the projections 16 of the member 14, so that the member 14and the core 1 may be rotated with relation to each other sufficientlyto bring the plates 3 and the projections 16 into such position as toentirely clear each other and allow the core 1 and the member 14 to becompletely separated. If the operation just described be now reversed itis obvious that the coupling may be returned to its locked position.

The raised portions 10 are concaved to fit the cylindrical surface ofthe core 1, and are of equal thickness with the plates 3, but are uponthe cylindrical surface of the core not of sutficient width to interferewith the movement of the core 1 just described; I their function beingmerely to form a wider bearing for the inner surface of the cap 6.

than would otherwise exist.

From the foregoing description it will be seen that we have providedacoupling easy of manipulation, sure in its action and which may beapplied to hose, line shaft-' ing, or other like elements with equalefficiency, and that no wrenches or other tools are necessary to coupleor uncouple the same.

We are fully aware that many minor changes in the details ofconstruction and arrangement of the parts will readily suggestthemselves to others skilled in the art, without departing from thespirit and scope of our invention, and we do not, therefore, desire tobe limited to the exact form of embodiment herein shown and described.

Having described our invention, what we claim as new, and desire toprotect by Letters Patent of the United States, is,.

conical end portion and with locking plates dly and ym etr a y di pcsthereon, said locking plates having each a radially projecting stud, andthe other of which cylinders is provided with an end adapted to fit thecone shaped end portion of said first named cylinder to make a fluidtight joint therewith and further provided with looking projectionsadapted to engage with said locking plates of said first named cylinder,and a collar having cam-slots and disposed on said first named cylinderwhich camslots are adapted to cooperate with said studs to forciblyengage said locking projections with said locking plates to rigidlyunite said cylinders, in combination with an annular cap associated withsaid collar and with said first named cylinder, said cap havinglongitudinally extending tongues adapted to prevent rotary movement ofone of said cylinders with respect to the other.
